Overview
The TCAN337DR, produced by Texas Instruments, is a 3.3-V CAN (Controller Area Network) transceiver that supports both standard CAN and CAN FD (Flexible Data Rate) protocols. This device is designed to be compatible with the ISO 11898-2 High Speed CAN Physical Layer standard, ensuring robust and reliable communication in various industrial and automotive applications. The TCAN337DR operates on a single 3.3-V supply, making it compatible with 3.3-V CAN controllers and microcontrollers, and it can also coexist with 5-V CAN transceivers on the same bus.
